Symbol loaded make Slow VS 2010, build project takes more time

when I build my web application it takes more time to build, I check in output, I see more symbol loaded. I have done the below things:

1. Tools -> Options -> Debug -> Just My Code

2. Tools -> Options -> Debug -> Symbol -> Checked -"All modules" and inside Specify Exclude Module, I have added "*.*."

But Still the same problem. All the tim sysmbol load and make application build very slow.

Please advice and help how can I avoid this problem.

Thanks in Advance.
